Be it known that I, ESAU D. TAYLOR, of Hornells amt smut ESAU n. TAYLOR, or HORNELLSVILLE, ew YORK, ASSIGNOR TO HIM- SELF. AND DAVID GOHN, OF SAME PLACE.

Letters Patent No. 101,541, dated April 5, 1870.

mnovemen'r m n'nr-nocx PL TE yille, in the county of Steuben and State of New York,

have invented a certain new and useful Improvement.

in Lock-Nut'Plates for Fish-Joints for Rails, and the manner of seeming the same; and the following-is a full, clear, and exact description of the same, reference being bad to the accompanying drawings making a part of this specification, in which-- Figure 1 represents a side view in abroken-ofi' section of fail, with a face view of-the lock-nutplate and fastener.

Figures 2, 3, and 4 show end sectional views of rail-'- joints, fish-plates, bolts, lock-nut plate, and fastener.'

Figure 5 shows the lock-nut plate detached. Figure 6 is a top view of the rail, with the joints secu'red'and the nuts looked on the bolts.

The object of my invention isto secure the nuts from turning ofl the bolts which hold the plates on.

the joints of rails in the most simple, cheap, and efiicient manner.

My invention consists in making along slit longiltudinally in the plate that is fitted onto the outside or square of the nuts, and-having a. bolt working loose in the fish-plate, so that-it will turn readily, the outer end of the bolt being joined into a right angle to pass through'the long opening in the lock-plate, and turn down byits own gravity, thus forming a butt-on, or

hook to hold the lock-plate on the nut, as hereafter more fully described, referring to the drawings and to the letters marked thereon. g The rails A'and the tie-bars B B, bolted on both sides.

of the rails, with two or more bolts, a a, with a head,

1), on the outcrend, and a nut, c, on the screw-thread end, which are technically termed fish-joints'for rails,'are made in the usual form and applied-in the usual manner.

My improved plates D may be made of band-iron, of any suitable width, orthey may be made of cast metal, with square holes (I (I through them, to nearly fit'on the nuts 0 c.

In the central portion,- or inany space between the nuts, I make a longitudinal slit, 0, of sulficient width to allowa bolt, f, whose pointed out-er end is bcntat about a right angle, to pass through the opening, when the angle is in a line with it, the bolt f being secured in the tie-bar B, so that it will turn easily, and allow the angle portion outside of the plate I) to turn down by its own gravity, and thus form abutton to secure,

the lock-nut plate in its place.

Many other devices have been applied and are now in use to some considerable extent, but none that have ever come to my knowledge are so easy-of operation, so simple and cheap in their oonstructiomand so decidedly efiicient for the purpose required.

I' do not claim, broadly, the lock-nut plateto fit the square of the nuts, held on by a staple and key, or the bending of plate metal over the edges of the plate, or othersimilar devices for fastening.

What-I do claim as my invention, and desire to secure by Letters Patent, is-

Securing the nut-lock plate D, by means of the slit e and button f, substantiallyas described.

In testimony whereof I have hereunto subscribed my name in the presence of-- ESAU D. TAYLOR. 1). L. BENTON, DAVID OoHY.
